Nrog rau kev nce hauv kev tsim tsheb thiab kev muag khoom, kev siv hluav taws xob thiab cov pa phem uas tsim tawm thaum lub sijhawm tsim khoom thiab siv tsheb tau nce ntxiv.Nyob rau tib lub sijhawm, kev ua qias tuaj rau ib puag ncig kuj tseem ceeb zuj zus.Yog li ntawd, txhawm rau txhawb kev txhim kho kom ruaj khov ntawm kev lag luam tsheb, raws li lub hauv paus ntawm kev ua kom muaj zog, lub zog, thiab kev nyab xeeb ntawm lub tsheb, los ntawm kev hloov cov khoom ntawm cov qauv tsheb thiab qhov chaw, qhov hnyav ntawm lub tsheb tau paub, uas yog ib qho tseem ceeb rau kev txhim kho cov roj efficiency ntawm lub tsheb thiab txo cov pa phem.Emissions muaj kev txhawb nqa loj heev.Lub tsheb sib zog tsis tsuas yog txuag lub zog thiab txo cov pa tawm, tab sis kuj txhim kho kev ruaj ntseg thiab kev ua haujlwm ntawm lub tsheb thaum tsav tsheb.Cov kab lus no feem ntau piav qhia txog magnesium alloy thiab aluminium alloy, uas tam sim no yog cov khoom siv dav siv hauv tsheb loj tshaj plaws, thiab tshuaj xyuas lawv cov yam ntxwv thiab qhov zoo, nrog rau kev txhim kho yav tom ntej ntawm tsheb sib tw.
Kev txiav txim siab los ntawm txoj kev loj hlob tam sim no, txhawm rau tiv thaiv ib puag ncig thiab txuag hluav taws xob thiab cov peev txheej, kev tshawb fawb thiab kev loj hlob ntawm lub tsheb yav tom ntej yuav tau them nyiaj ntau dua rau cov qauv tsim ntawm lub tsheb.Kev siv cov khoom siv hnyav xws li cov hlau muaj zog, aluminium alloy, magnesium alloy, thiab cov ntaub ntawv sib xyaw hauv kev tsim tsheb tuaj yeem ua tiav lub tsheb hnyav.Tsis tas li ntawd, kev tsim cov txheej txheem siab heev xws li kub sib sau, laser tailored vuam, hydraulic sib sau, thiab lwm yam kuj siv tau.Lub tsheb hnyav.Aluminium alloy tau siv dav hauv tsheb sib zog dhau los ntawm nws cov txiaj ntsig xws li ceev ceev, zoo corrosion tsis kam thiab ua tau yooj yim.
Aluminium yog lub teeb hlau uas muaj hluav taws xob zoo thiab thermal conductivity, nrog rau zoo corrosion kuj.Nyob rau tib lub sijhawm, kev ua haujlwm zoo ntawm aluminium alloy zoo dua li cov khoom siv hlau tsoos.Aluminium muaj qhov qis melting point.Tus nqi rov qab ntawm txhuas thaum lub sij hawm tag nrho kev siv thiab rov ua dua txheej txheem tsis tsawg dua 90%.Aluminium alloy muaj cov khoom tsim tau zoo heev, yog li Aluminium alloy tam sim no yog cov khoom siv zoo tshaj plaws kom paub txog lub teeb ntawm lub tsheb.
Kev siv aluminium alloy qhov chaw hauv tsheb tuaj yeem txo qhov hnyav ntawm tag nrho lub tsheb, txo qhov nruab nrab ntawm lub ntiajteb txawj nqus ntawm lub tsheb, thiab paub tseeb tias lub teeb yuag ntawm lub tsheb.Tom qab qhov hnyav ntawm lub tsheb raug txo, qhov kev ua haujlwm nrawm ntawm lub tsheb yuav raug txhim kho nyob rau hauv kev tsav tsheb, thiab lub tsheb yuav ruaj khov thiab xis nyob, thiab lub suab nrov thiab kev co kuj yuav raug txhim kho.
Daim ntawv thov ntawm aluminium alloy nyob rau hauv lub tsheb lub teeb yuag mas muaj xws li txhuas alloy forgings, hlau tuag castings, aluminium alloy extrusion thiab kos duab khoom, thiab lwm yam.
Cam khwb cia aluminium alloy yog siv dav tshaj plaws hauv cov txheej txheem tsheb sib tw tam sim no.Nws yog tsuas yog siv nyob rau hauv lub tsheb cav, chassis, log hub thiab lwm yam qauv.Lub cav tau raug hu ua "lub siab" ib feem ntawm lub tsheb, nyob rau hauv lub tog raj kheej taub hau, lub tog raj kheej thaiv, piston, thiab lwm yam. Daim ntawv thov ntawm txhuas alloy mus rau qhov chaw yuav tsis tsuas zoo txo lub zuag qhia tag nrho lub cev hnyav ntawm lub cav, tab sis kuj dissipate lub Thaum tshav kub kub generated nyob rau hauv lub cav ua hauj lwm nyob rau hauv lub sij hawm los txhim kho kev ua hauj lwm efficiency ntawm lub cav
Lub weldability ntawm aluminium alloy daim ntawv yog phem dua li ntawm cov hlau thaum siv, uas txhim kho cov vuam kev ua tau zoo thiab vuam zoo ntawm aluminium alloy daim ntawv, thiab ua rau cov ntaub ntawv ntau ntawm aluminium alloy.Daim ntawv thov ntawm cov txheej txheem kub txheej txheem, superplastic forming technology thiab electromagnetic coincidence forming technology los txhim kho formability thiab tsim zoo ntawm aluminium alloy panels.
Tam sim no, ntxiv rau cov khoom siv aluminium alloy hlau, aluminium-raws li cov ntaub ntawv sib xyaw tau siv dav hauv kev tsim tsheb tsim vim lawv qhov zoo ntawm qhov tsis tshua muaj siab, siab zog, thiab siab corrosion kuj.Piv nrog rau cov tsoos cam khwb cia hlau pistons, tsheb cav pistons txo lawv qhov hnyav li ntawm 10%, thaum lawv cov cua kub dissipation kev ua tau zoo yog nce 4 zaug.Kev txwv los ntawm tus nqi thiab kev tswj kom zoo, aluminium-based composites tseem tsis tau tsim cov nplai loj, tab sis tau qhia lawv cov kev ua tau zoo ntawm qee qhov chaw pib.
Nyob rau niaj hnub no txoj kev loj hlob sai ntawm kev lag luam thiab kev sib raug zoo, ntsib teeb meem tshiab ntawm lub zog thiab teeb meem ib puag ncig, cov tsheb sib zog tuaj yeem txhim kho cov roj efficiency ntawm cov tsheb, yog li txo cov pa phem.Nyob rau hauv cov txheej txheem ntawm automotive lightweighting, magnesium alloys, aluminium alloys thiab lwm yam ntaub ntawv hlau tau dav siv vim lawv qhov zoo thiab cov yam ntxwv.Nyob rau hauv lub neej yav tom ntej, kev txhim kho thev naus laus zis yuav raug siv los txo cov nqi ntawm cov khoom siv, nce kev siv cov khoom siv, thiab txhim kho ib puag ncig tus phooj ywg thiab cov khoom siv tau.Cov khoom siv rov ua dua tshiab kuj tseem yog ib qho kev tsis pom kev hauv kev tshawb fawb thiab kev loj hlob ntawm lub tsheb hnyav.
